Multiple-input multiple-output (MIMO) wireless communication technology has observed remarkable growth, moving from a research concept to widespread implementation in just over 10 years. But MIMO finds its roots in antenna diversity, whose history starts back in the 1920s. This paper provides a brief summary of the history of antenna diversity and MIMO systems, emphasizing some of the key associated...
A recent method has been proposed for determining the optimal radiation characteristics of antennas that maximize the diversity gain for a given antenna aperture and power angular spectrum of the incident field. However, because this approach results in antennas whose current distributions overlap in the aperture, it is difficult to achieve the radiation characteristics using practical designs. This...
